Application filed March 8,1921. Serial No. 450,752.

To all Lo/1,0m it mwg/ concern Be it known that l, Moens li". Gann, acitizen of the United States, and a resident of Newton, in the county ofMiddlesex, Commonwealth of ll/Iassachusetts, have invented anImprovement in Fasteners, of which the following description, inconnection with the accompanying drawings, a specification, likecharacters on the drawings representing like parts.

rlhis invention pertains to improvements in fasteners, and moreparticularly, though not exclusively, to fasteners of the threeside locktype. It is among the objects of the invention to provide an improvementin the securing of the sockets of three-side lock fasteners to theircarrying fabrics.

ln the drawings, which show a preferred embodiment of one form of myinvention Figure 1 is a front elevation of a socket, a portion of thecarrying fabric being shown;

Fig. 2 is a section on the line 2 2 of Fig. 1;

Fig. 3 is a diagrammatic section :illustrating the portions of thefastener prior to securing thereof to the carrying fabric andillustrating' a preferred form of die for et fecting the securingoperation; and

Fig. 4 is a. section through the socket on the line 41 of Fig. 2.

Referring to the drawings and to the preferred form of my inventionselected for illustrative purposes, l have shown a socket( whichpreferably, as illustrated, includes a casing 5 containing a spring 6and provided with a front plate 7. The casing o is preferably providedwith a stud-receiving opening 8, and provided with an underlying' lip 9.The stud-engaging portion of the spring 6 intersects a portion of thisstud-receiving opening so that the spring may engage the neck of thestud beneath the head thereof to hold the stud and socket in engagement.The front plate 7 of the casing is prefer ably, as illustrated, providedwith a forward extension 10 having an inwardly flanged lip 11 andproviding an aperture to receive the tubular rivet 12 projecting fromthe securing means on the other side of the socket-carrying fabric 13.

ll`he securing means preferably includes a plate 111, from which thetubular rivet 1Q projects, and a covering plate 15. Theplate 1l, priorto assembly of the parts, is preferably dished in the direction of theproie@ -tion of the tubular rivet 12, as best shown 1n Fig. 3, and themarginal portions thereof underlie the flange 16 of the coverin.Dr plate15, closely fitting the same. lllhen thce parts are to be assembled.they are placed .in the relationship shown in F 3 and the upsetting die'i7 is introduced through the stud-receiving aperture of the socket, thehead thereof being preferably rounded to move the studengaging springout of the Way. A supporting die 18 backs up the covering plate 15 and,as the two dies are forced together, the plate 'la is sprung' so that itdishes in the opposite direction from that illustrated in Fig. o andassumes the position shown in Fig. 2 as the tubular rivet is upset bythe die 17. The upsetting of the rivet holds the parts in assembledrelation ship, and the reversal of the dishing of the plate carrying thetubular rivet results in great pressure being exerted to grip the clothbetween the marginal portions of the socket and the marginal portions of`the socket-securing parts on the opposite side of the fabric 13. i

llVhen the die 17 is removed after the comn pletion of thesocket-securing operation, the stud-engaging spring resumes its normalposition and the socket is ready `for use. 1When the ystud entered inthe socket. the head of the stud may engage the projecting portion l()of the socket casing. l have not described the operation of the stud andsocket more fully, such description being unnecessary because. so far asthe cooperation of the stud and socket is concerned` the construction isfully described in United States Patent No. 1,278,798, issued September10. 1918, to Carr Fastener Company, assignee of Fred S. Carr. lt will beunderstood, however, that my invention may be of use in connection withother types of fastener.

`While I have shown and described a preferred form of one embodiment ofmy in! vention, it will be understood that maior changes involving`omission, substitution, lalteration and reversal of parte, and evenchanges in the mode rof operation. mav be made without departing fromthe/scope of my invention, whichis best defined in the following claim.

Claim.

In testimony whereof, I have signed my name to this specification.
